Definitions
- This invention relates to continuous bulk unloaders/reclaimers (herein afterward referred to as continuous unloaders) that use a digging chain to reclaim and convey granular or powder bulk materials such as grains, coal, ores, fertilizers, rocks, soil, etc. from pits, stockpiles, and the cargo holds of vessels such as ships, barges, railcars, and the like.
- U.S. Patent #3,144,142 introduced an unloader for ships that utilized a digging chain that reclaimed cargo as it pulled through the cargo in a digging loop. This patent was further improved upon by U.S. Patent #3,378,130.
- the present invention will introduce additional means for improving digging chain unloader performance.
- Figure 1 shows a schematic drawing of my improvement for deflecting the bucket conveyor chain outward prior to forming the digging loop.
- Figure 2 is a schematic view of the lower part of figure 1 and shows the digging loop of the bucket chain with a plate to protect the chain from avalanches of the cargo.
- Figure 3 is a cross sectional view along line 3-3 of Figure 2.
- Figure 4 shows a variation of how to mount the plate of figure 2.
- Figure 5 shows a variation of the plate of figures 2 and 4 which has wheels added to help guide the bucket chain.
- Figure 6 is a cross sectional view along line 6-6 of figure 5.
- Figure 7 is a variation of figure 5 with a plurality of plates, arms, and wheels.
- Figure 8 shows a pivot arm with a guide wheel attached for tracking the chain in the digging loop.
- Figure 9 is a variation of figure 8 with added items to assist protecting and guiding the chain as it traverses the digging loop.
- Fig. 1 shows a continuous unloader according to the preferred embodiment of the invention.
- the unloader is comprised of a support structure 1 which supports a bucket conveyor frame 3 which supports a plurality of wheels.
- the plurality of wheels support and circulate a bucket conveyor chain 13.
- the bucket conveyor frame 3 is lowered into a vessel's hold 9 where its bucket conveyor chain 13 circulates in a manner to reclaim, elevate, and transfer the cargo 1 1 to a discharge conveyor 5 which removes the cargo 1 1 for storage, etc.
- the bucket conveyor frame 3 wheel's include an exit wheel 17 which directs the bucket conveyor chain 13 outward and down to guide wheel 19.
- a control wheel 27 is interposed between exit wheel 17 and guide wheel 19 to help guide the bucket conveyor chain 13.
- Guide wheel 19 directs the chain 13 downward into a digging loop 15 which is used to fill the buckets of the bucket conveyor chain 13 by dragging them through the cargo 11.
- the bucket conveyor chain 13 is gathered by gather wheel 21 and directed to a deflecting wheel 23.
- An intermediate wheel 25 is interposed between gather wheel 21 and deflecting wheel 23 to help guide the bucket conveyor chain 13
- Deflecting wheel 23 directs the chain 13 upward to upper wheel 7 where the cargo is then discharged onto the discharge conveyor 5.
- the upper wheel 7 directs the chain 13 downward to the exit wheel 17 thereby completing one complete circuit of the bucket conveyor chain 13.
- the wheels are mounted to the frame by conventional shafts and bearings so that the bucket conveyor chain 13 runs inside the bucket conveyor frame 3 wherever possible to control dust and spillage.
- the improved unloader is further comprised in the area of the digging loop 15 between guide wheel 19 and gather wheel 21 with additional components to stabilize, track, and protect the digging chain 13 as it traverses through the digging loop 15. More specifically after the bucket chain 13 is deflected downward to form the digging loop 15 by the guide wheel 19 it is protected from cargo 11 that would fall directly on top of it by a plate/support frame 29.
- the plate/support frame 29 is connected by a hinge 31 to the bucket conveyor frame 3.
- An actuator/dampener 34 is connected between the plate/support frame 29 and the bucket conveyor frame 3 to control the position and motion of the plate/support frame 29.
- a support chain 32 is also connected between the bucket conveyor frame 3 and the plate/support frame 29 to control the extreme position that the plate/support frame 29 can travel.
- Detectors 45 comprised of a vertical structural member are attached to the plate/support frame 29 to prevent the conveyor bucket chain 13 from being crushed between the plate/support frame 29 and the cargo 11 in the event that the bucket conveyor frame 3 is lowered to quickly down into the
- the plate/support frame 29 is located adjacent to the bucket conveyor chain 13.
- FIG 4 a variation of mounting the plate/support frame 29 is shown where the hinge 31 of the plate/support frame 29 can be connected to an arm 33.
- Arm 33 is hinged to the frame 3 via an arm hinge 35.
- the actuator/dampener 34 is connected near the plate hinge 31 to control the position and movement of the arm 33 which in turn controls the position and movement of the plate/support frame 29.
- Support chains 32 are connected between the frame 3 and the plate/support frame 29 to control the extreme position of the plate/support frame 29.
- a plurality of wheels 37 can be added to the plate/ support frame 29 of figure 4 to help guide and track the bucket conveyor chain 13 as it traverses through the digging loop 15 of figure 1.
- a wheel cover 43 surrounds wheels 37 to protect them from damage and stalling from cargo avalanches.
- wheels 37 are mounted to the plate/support frame 29 via an axle 39 and a bearing 41.
- the axle 39 is extended outward to form a pin for mounting the plate/support frame 29 to the arms 33.
- Detectors 45 comprised of a vertical structural member are attached to the plate/support frame 29 to prevent the conveyor bucket chain 13 from being crushed between the plate/support frame 29 and the cargo 11 in the event that the bucket conveyor frame 3 is lowered too quickly down into the cargo 11.
- FIG 7 a variation of mounting the plate/support frame 29 is shown where it is divided into a plurality of plate/support frames 29 each supported independently of the other. Wheels 37 are attached to the plurality of plate/support frames 29.
- a single wheel 37 can be attached directly to a arm 33 without being supported by the plate/support frames 29 shown in the above described figures.
- a single wheel 37 can be attached to a plate/support frame 29 without using a plurality of wheels 37 as shown in figures 5 and 7.
- the frame 3 surrounds the bucket chain everywhere except in the vicinity of the digging loop. This protects the digging chain from damage and contains dust.
- the support structure 1 holds the bucket conveyor frame 3 adjacent to the cargo 11 in the vessel's hold 9.
- the support structure 1 can be mobile or fixed. It functions to allow the bucket conveyor to be movable inside the vessel's hold 9, and from hold to hold, and from one vessel to another.
- the bucket conveyor chain 13 is supported, circulated, and guided by the wheels 7, 17, 27 19, 21, 25, 23. The said wheels can be powered or idlers as required. They are attached to the bucket conveyor frame 3 by conventional means utilizing bearings, shafts, couplings, motors, etc. which are not shown.
- the bucket conveyor chain 13 drags through the cargo 11 as they traverse the digging loop 15.
- the bucket conveyor chain 13 then elevates the cargo up and over wheel 7 where a combination of gravity and centrifugal force are used to dump the cargo out of the bucket conveyor chain 13 onto the discharge conveyor 5 where it is removed from the unloader.
- the first two functions are taught by prior art.
- the first function being to form the bucket conveyor chain 13 into a digging loop 15 as provided by wheels 19 and 21.
- the second function being to move the bucket conveyor chain 13 more or less vertically upward as provided by wheel 7, 17, and 23.
- the 3 rd function and newly invented function is to provide a lateral extension horizontally outward and downward of the bucket conveyor frame 3 so that the digging loop 15 can reach into the far corners of vessels and under hatch combing without being excessively long and floppy.
- a long digging loop 15 can make it very difficult to track and guide the bucket conveyor chain 13.
- the inclined portion of the frame between wheels 21 and 23 is positioned in close proximity of the bucket conveyor chain 13 to control reclaimed cargo spillage from the bucket conveyor chain 13 while it travels up the incline from gather wheel 21 to deflecting wheel 23.
- a plate/wheel support frame 29 that is located adjacent to the top of the bucket conveyor chain 13.
- the plate/wheel support frame 29 has a plate hinge 31 that hinges it to the bucket conveyor frame 3 so that it is flexible.
- a support chain is attached to the bucket conveyor frame 3 at one of its ends and to the plate/wheel support frame 29 at its other end. This controls the extreme position of the plate/wheel support frame 29.
- An actuator/dampener 34 is connected between the bucket conveyor frame 3 and the plate/wheel support frame 29 to control its position and dampen out unwanted motion.
- a detector 45 is attached to the plate/wheel support frame 29 to protect the bucket conveyor chain 13 from being crushed between the plate/wheel support frame 29 and the bottom of the vessel's hold 9 or the cargo 11. Should the bucket conveyor frame 3 be lowered too quickly or too far down into the cargo 1 1 or hold 9 the detector will push up on the plate/wheel support frame 29 allowing relief.
- the actuator/dampener 34 can be used to help lift the plate/ wheel support frame by acting as a counterbalance.
- an alternative way to attach the plate/wheel support frame 29 of figure 2 is to connect one end to an arm 33 by a hinge 31.
- the arm 33 is connected at its other end by a hinge 35 to the bucket conveyor support frame 3.
- a support chain 32 is added at both ends of the plate/wheel support frame 29 to control its extreme positions.
- the actuator/dampener 34 is attached by the a hinge 31 to control both the arm's 33 and plate/wheel support frame's position and dampen out unwanted motion.
- the other components of figure 4 function in the same way as those described above for figures 2 and 3.
- tracking wheels 37 are mounted to the plate/wheel support frame 29 so that they contact and prevent the bucket conveyor chain 13 from sliding over the plate/wheel support frame 29. This reduces bucket conveyor chain wear due to friction. These wheels 37 also help to guide and track the bucket conveyor chain 3 when the bucket conveyor frame 3 is moved laterally through the cargo or when an avalanche pushes sideways on the bucket conveyor chain 3.
- a cover 43 is provided each of the wheels to prevent them from being engulfed by cargo avalanches.
- the other components function as described above for figures 2,3, and 4.
- a plurality of plate/wheel support frames 29 can be used in place of the single plate/wheel support frame. These would function as described above for figures 2 through 7 and would have some or all of the components described for those figures.
- a guide wheel 37 is directly attached to the arm 33 without the use of plate/wheel support frame 29 as described in previous figures.
- a support chain 32 is between the arm 33 and the support frame 3 to control its extreme positions.
- a plate/wheel support frame 29 can have only one guide wheel attached to it. It would function as described above for figure 5. While the above description contains many specifics, the reader should not construe these as limitations on the scope of the invention, but merely as examples of preferred embodiments thereof. Those artisans skilled in the art will envision many other possible variations that are within its scope.
